Availability date:
The HOBO Water Level data logger features high accuracy at a great price and ease-of-use, with no cumbersome vent tubes or desiccants to maintain. This data logger is ideal for recording water levels and temperatures in shallow wells, streams, lakes and freshwater wetlands. For saltwater deployments, such as brackish wetlands and tidal areas, see HOBO U20 Water Level Titanium.
Environment: The U20-001-01 Data Logger is for use in Outdoor and Underwater environments
Measurements: The U20-001-01 Data Logger supports the following measurements: Temperature, Barometric Pressure, Water Level
